SUMMARY:Seminar Analysis and Mathematical Physics: Roman Shvydkoy (Universi
 ty of Illinois at Chicago)
DESCRIPTION:The classical Kolmogorov-41 theory of turbulence is based on a 
 set of  pivotal assumptions on scaling and energy dissipation for solutio
 ns satisfying incompressible fluid models. In the early 80's experimental 
 evidence emerged that pointed to departure from the K41 predictions\, whic
 h was attributed to the phenomenon of statistical intermittency.  In this
  talk we give an overview of the classical results in the subject\, relati
 onship of intermittency to the problem of global well-posedness of the 3D 
 Navier-Stokes system\, and discuss a new approach developed jointly with A
 . Cheskidov on how to measure and study intermittency from a rigorous pers
 pective.  At the center of our discussion will be a new interpretation of
  an intermittent signal described by volumetric properties of the filter
 ed field.  It provides\, in particular\, a systematic approach to the Fr
 isch-Parisi multifractal formalism\, and recasts intermittency from the po
 int of view of information theory.
